IBM mainframes do not have a ZIP utility available by default. Hence what you want to do pretty much cannot be done as specified.
One option would be to use the Unix System Services (USS) pax command which is available on Unix systems and does similar things to pkzip. Your site may have gzip / gunzip as well in USS -- you would have to ask your site support to know for sure.
